Sorry, but it is a big NO. We already have too many players not paying attention about that, only to regret later for complaining that they lost Porygon, Jirachi and so on forever. Relying on the 1/1000 Roaming Encounter as your second chance is a very bad idea. Besides, as DaD0ge said, there are other Pokemon like Porygon and Snorlax which do not go Roaming, but are still once only.
